When more charge current
is required than can be con-
trolled by one Dingo, then
the array can be split. Dingo
Pups can carry the current
from these extra sub arrays.
The way this is set up is
shown in fig.6 on page 15.
The Dingo controls the
Pups. It tells them when to
turn on or off. When the
battery voltage is below
the regulation point, all
Pups will be on. When
the battery voltage gets to
the regulation point, the
Dingo will turn off the Pups
progressivly to reduce the
charge current so as to
maintain the regulation volt-
age. If the load increases or
the insolation reduces, then
Pups will be turned back on
until a balance is restored.
The Expanded Dingo System
The Pups report back their
current to the Dingo which
displays the total current in
the system. It also shows
the individual contibutions
from each device.
The Dingo and the Pups are
connected together with a
cable. If a Pup becomes dis-
connected from the cable,
then it will regulate like an
independant Dingo.
A system based on a Dingo
2020N is negative ground.
This means that the battery
negative terminals are all
connected together. Switch-
ing is done on the positive
side.
A Pup may also be operated
as an external switch, con-
trolled by the event, alarm
or load disconnect outputs
of the parent Dingo.
